need some ideas on this (any)

[bubbakat]

I have this 15ft flat bottom boat maker unknown.<br />Fiberglass with wood seats and wood transom. <br />What I need is some good ideas on how to either raise the transom or just the motor.<br />This boat is very steady in the water and has plenty of room. The 9.5 on the transom is sitting a little to low. The anticavation plate is about three inches to low and I need to raise it. Let me here any and all ideas.<br />

Is it a short shaft or a long shaft engine? If its a long shaft, convert it to a short shaft. Otherwise you could glass in a piece of wood (sort of like an extension of the wood that is on there now) to raise the top of the transom in the middle 3 inches. It wouldn't be hard just some plywood, epoxy, and glass.

I agree, replace that bit of wood (looks like laminate flooring!) with a new bit of 3/4" ply, 3" taller, double thickness at the top so there's a lip that sits on top of the transom.<br />I'd also add a piece of ply, 3/8" or maybe 1/2" to the outside. Epoxy the whole lot to the transom and bolt right through with S/S or hot dip galvanized bolts, so the glass transom is rigidly sandwiched between the inner and outer ply.<br />That'll raise your motor and provide a really stiff motor mount.<br />If you have some to hand, or if your budget allows, use marine ply. If not use good quality exterior and give it a couple of coats of epoxy resin to seal it whichever you use.

bubbakat, I wouldn't make anything permanant incase your not happy with performance. My old 30 hp was low and after reading post I decided to raise motor to where c/p was even with bottom of boat. No differance in speed at all. What I did encounter was taking off at wot the prop would loose its bite and I would have to back off throttle and ease throttle. Then, at wot I could turn to port ok but starboard turns same thing, prop would lose its bite. Took my homemade extension off and nomore prop problems.<br />Before I took extension off I did try all 4 trim settings on the motor.<br />BTW, Iv'e Got that same 9.5 on a 10 ft. jonboat. You talk about something that will scream across the water. WOW.

Thanks guys for the ideas. I am going to fashion me a jack plate out of some alum. angel iron and try my idea of the performance and like-cajun said if I don't like it I will remove it. If it does work good I will raise the transom as suggested in the other posts.<br />You are right about one thing cajun those 9.5 will scream. I love the way this thing pushes that boat thru the water. With a new impeller and a new head gasket I have a grand total of $65 in this thing. It is hard starting ---- you have to pull the rope at least half way out
